zhengtianzuo系列-C++/Qt/Qml程序使用Camel_CrashReport捕获异常崩溃并定位问题代码行***#### 组件介绍: *** ###### Camel_CrashReport: 程序异常崩溃时生成Dump文件和日志, **非开源** 属于CamelSoft系列基础开发组件. Dump文件是进程的内存镜像。可以把程序的执行状态通过调试器保存到dump文件中。 支持平台：Windows *** *** CamelCrashReportTest: 崩溃报告开发组件测试程序 Camel_CrashReport的调用非常简单, 提供了三个接口: ``` int Cls_funCrashReportInitialize();//初始化 ``` ``` int Cls_funCrashReportTerminate();//销毁 ``` ``` int Cls_funGetException(PEXCEPTION_POINTERS pExceptPtrs, WORD srtParam);//捕获崩溃 ``` 首先引用接口文件和定义函数指针, 这是加载dll动态库的过程 ``` //Camel_CrashReport函数指针 #include <Windows.h> #include "../../include/CamelCrashReportDll/Camel_CrashReport.h" HINSTANCE hCrashReport; lpCls_funCrashReportInitialize funInitialize; lpCls_funCrashReportTerminate funTerminate; lpCls_funGetException funGetException; ``` 然后初始化组件: ``` //初始化Camel_CrashReport hCrashReport = LoadLibrary(L"Camel_CrashReport.dll"); funInitialize = NULL; funGetException = NULL; funTerminate = NULL; if (hCrashReport != NULL) { funInitialize = (lpCls_funCrashReportInitialize)GetProcAddress( hCrashReport, "Cls_funCrashReportInitialize"); funGetException = (lpCls_funGetException)GetProcAddress( hCrashReport, "Cls_funGetException"); funTerminate = (lpCls_funCrashReportTerminate)GetProcAddress( hCrashReport, "Cls_funCrashReportTerminate"); funInitialize(); } ``` 使用__try __except 包裹主函数 ``` __try { #endif init(argc, argv); #ifdef WIN32 } __except (funGetException( GetExceptionInformation(), clsCrashReport_intParam_Normal)) { ; } ``` 程序执行结束时卸载组件 ``` if (hCrashReport != NULL) { funTerminate(); funInitialize = NULL; funGetException = NULL; funTerminate = NULL; FreeLibrary(hCrashReport); hCrashReport = NULL; } ``` 就这三步就ok了 然后程序运行时, 执行异常崩溃的代码 就会触发写dump文件和日志的过程 ``` //运行异常代码 char* chr = NULL; memset(chr, 0, 10); ```   生成的dump文件可以直接用VS打开并调试  异常崩溃时生成的dump文件, 在VisualStudio下调试直接定位到代码行, 当然也可以使用WinDbg调试 生成的txt日志文件包含很多有用的信息  注意: 如果是Qt/Qml工程要正确的定位到崩溃代码行, 工程需要使用VisualStudio编译 参看 Qt/Qml工程转VS工程 需要完整代码请访问 Camel_FileManagerCExamples |
